One nice thing about electronics is that you know pretty soon whether you're right or not. Another is that you can finish one thing and move on to another. John

Friedman's book "Hot, Flat and Crowded". I read Friedman's book. My word but he's an illogical, histrionic fool. Not sure if I finished it--once I saw his rationale assembled, it grew too tedious to watch him extrapolate ever more fantastical consequences.

I thought it was more than good enough of an approximation for a back- of-the-envelope estimate of a ~20% factor. Engineers do stuff like that. And, I got within 1.5%, for an overall error contribution of < 0.3%. Or did you mean it was a mistake for me to depend on something I thought I might've heard from you? -- Cheers, James Arthur

I understood you perfectly Jan, if it makes you feel any better. A few others didn't, but I guess that's just a hazard of internet and text postings. -- Cheers, James Arthur
